HEATING-STOVE Specification of Letters Patent.

Patented Nov. 12, 1907.

Ap lication filed March 28,1907. Sena No. 365.002.

To all whom it may concern:

Be it known that l, ELISHA WILLIAM BABCOCK, a citizen of the United States, residing at Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in H eating-Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

. This invention relates to improvements in heating stoves.

The object of the invention is to provide a heating stove having a centrally-disposed air heating passage extending through the same whereby the air passing thercthrough is thoroughly heated without coming into contact with the flames from the burner or heating mechanism.

A further object is to provide a stove of this character so constructed andarranged that none of the burned gases or products of combustion may mix with the air in the room or apartment being heated, said burned gases being conducted from the combustion chamber to the flue of the chimney by a suitable conducting pipe.

With the foregoing and other objects in view, which will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a side elevation of the heating stove constructed in accordance with the invention; Fig. 2 is a vertical longitudinal sectional view; and Fig. 3 is a vertical cross-sectional view of the same.

Referring more particularly to the drawings, 1 denotes the stove consisting of an outer casing 2 which is preferably of flat oblong shape and provided at its lower end with an enlarged combustion chamber 3 in which is arranged the heating device which is here shown as a burner pipe 4 provided on its upper side with a series of burner openings. The pipe 4 extends entirely around the chamber 3 in the form of an elongated loop."

Arranged in the outer casing 2 is an inner wall or casing 5 which is open at its upper and lower ends to provide a passage 5 through which the air passes'and is heated by the flame from the burner pipe 4. The space between the inner casing 5 and the outer casing 2 is closed at its upper end, said closure being preferl l l l l a ably formed by providing right-angular-outwardly projecting flanges 6 on the upper edges of the inner and outer casings, said flanges being connected together at their outer edges, as shown. With the flanges 6 on the inner casing and preferably at the center of one side thereof is connected a conducting pipe 7 through which the burned gases and products of combustion from the combustion chamber 3 are carried off and discharged into a chimney.

The lower portion of the inner casing 5 within the combustion chamber 3 and immediately above the burner pipe 4 is bulged or projected outwardly as shown at 8, said bulged or projected portion forming a baffle plate above the burner pipe so that the flame therefrom is caused to come into contact therewith and pass around the same and thereby intensely heating said inner casing so that the air passing through the latter will be quickly and thoroughly heated while passing upwardly through the stove.

The stove is supported at its lower end upon suitable legs 9 so that the air in the room may readily pass beneath the same and upwardly through the heating passage of the inner casing and into the combustion chamber to supply the burners with the proper amount of air. The air after passing into the combustion charm her in contact with the flames therein will pass on upwardly through the upper portion of the space between the inner and outer casings of the stove, heating said casing and from thence passing outwardly through the conducting pipe to the chimney without entering the room or coming into contact with the heated air in the inner passage of the stove. The lower portion of the inner casing below the bulged or outwardly-projecting sides 8 of the same is contracted to a narrow passage through which the air to be heated is drawn.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing'from the principle or sacrificing any of the advantages of the invention, as defined by the appended claim.

Having thus described my invention, what I claim as new is, I

A heating stove comprising an outer casing having an enlarged lower end to form the outer wall of a combustion chamber, and arranged at its upper end to form two heat conducting chambers, an inner casing arranged at its upper end to form air conducting tubes within said heat conducting chambers and having an open reduced lower end above which said inner casing is bulged to form a baflie or heat deflecting projection, a burner pipe arranged below said projection, a perforated bottom'to cover the space between the lower end of said outer and inner casings, and parallel radially projecting flanges formed on the upper ends of said inner and outer casings, said flanges having inwardly turned edges adapted to be secured together to close the upper end of the heat chambers, substantially as 10 described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
